Striker Steve Torpey will return to Scunthorpe's squad after a month out with a thigh strain.
Winger Ian Morris (knee) and defender Marcus Williams (ankle) face late tests, Robbie Foy, Jim Goodwin and Cliff Byrne standing by.
Wrexham injury returnees Juan Ugarte (knee) and Lee McEvilly (foot) are expected to take bench places.
"He (Ugarte) is still along way short of match fitness," said manager Denis Smith. "But as with Lee McEvilly last week against Lincoln City, he gives me another option to bring on for a short spell at the end of the match.
"Lee is getting stronger with each day, so it's another step towards getting the strength of squad back to where it should be."
Neil Roberts and Matt Done are still out (ankle injuries), but Kevin Smith hopes to shake off a viral infection
